Abstract

The invention relates to amino polyester polyether castor oil, a preparation method and application of the amino polyester polyether castor oil. The amino polyester polyether castor oil is prepared from castor oil, maleic anhydride, glycol, composite catalyst, thionyl chloride and primaryaliphaticamine. When in use, the amino polyester polyether castor oil is mixed with polyaryl polymethylene isocyanate (PAPI) according to mass ratio of 1:1, and the mixture is evenly coated on the surface of bonded material by an automatic continuous forming machine or intermittent-type process route, whereinthe glue application dosage is 0.5kg / m<2>.

Description

technical field [0001] The invention relates to an amino polyester polyether castor oil and its preparation method and application, belonging to the technical field of polymer synthesis chemistry. Background technique [0002] Amino polyether (Amine Terrninated Polyether) is a class of polyoxyalkylene compounds terminated by primary or secondary amino groups. Since the amino group at the end of the amino polyether molecular chain contains active hydrogen, it can quickly react with isocyanate to form polyurea, and the reaction speed of isocyanate with primary or secondary amino groups is greater than that with alcoholic hydroxyl groups and with water. Therefore, a On the one hand, the curing speed of polyurea is faster than that of polyurethane, and no catalyst is needed in the preparation process. On the other hand, polyurea is less affected by the environmental humidity during construction. Polyurea has strong adhesion to metal and non-metal substrates, such as steel, alum...
